Yes, your account should transfer.
Buy a wireless router. Buy an Xbox 360 Wireless Adaptor if you have the old xbox, but dont if have the slim one. Go to "Join Xbox Live" in your Xbox 360 Guide (Press the xbox logo on your controller). Follow the on-screen instructions.
You don't actually get Xbox Live on a PS3, the network for the PS3 is called the PlayStation network (creative). To connect you need an internet connection and a membership. I am currently on the XBox 360, so the details of how to connect aren't my area of expertise...
no you can only go on 3 xbox games live on 360 halo2, pgr3 and battlefield.
No.
on xbox 360 you can go on xbox live.
Yes its just the same.
make sure you have a router ( wireless or wired ) then connect you Ethernet wire/cable to the router and one to the xbox 360 the go to connect live
If it is available on the 360 then as long as you have an Xbox Live Gold membership you should be able to go on multiplayer no problem. Same goes for the xbox one
You will need to be live but I think you can be a silver member to do this.
elite has much more space for games and is the only way to go if u play on live
yes your membership will go with your profile but you cannot go from xbox to 360
no an ethernet cable will do
